Negative Emotion Differentiation through a Developmental Lens: Associations with Parental Factors and Age in Adolescence.

Negative emotion differentiation (NED) is the ability to precisely discern negatively-valenced emotional states. Low NED has been linked to numerous negative outcomes. However, little is known about the conditions under which individual differences in NED emerge, particularly during adolescence, a potentially important developmental stage. We examined associations between NED (assessed using intraclass correlations between negative emotion [NE] ratings collected via intensive longitudinal methods), parental variables, and age. Adolescents (=233, =15.90, 53% female) and their parents completed interview measures of depression and self-report questionnaires; adolescents then completed a seven-day ecological momentary assessment. Lower NED was associated with greater parental depression, greater authoritarian parenting style, and lower parental attachment security. Age was negatively and linearly associated with NED. Results held controlling for mean NE and adolescent depression, although authoritarian parenting was non-significant controlling for other developmental variables. Findings suggest healthy parent-child relationships may relate to adolescents' ability to perceive NEs with nuance.
